This was to be a follow-up of sorts to the Toho/Tsuburaya co-production DAIGORO VS. GOLIATH, utilizing modified outfits from that movie, but with a new origin. In the proposed story, two monsters, Redmoon and Erabus, produce a child-monster, Hanfun, which is killed by humans. When the parents go on a rampage, it’s up to Godzilla to stop them.
